old, but good, paint/drywall mud (Lakewood, CO)

I have a condo i've been renovating in the green mountain area of lakewood that has gone a little over budget. In an effort to try and save some money I am looking for any old, but still good, paint that you have lying around. Interior wall/ceiling paint,l drywall primer/kilzas, 123 primer. Any drywall mud would be much appreciated as well!

Thank you in advance for your help!
